Subject: [PATCH v5 0/6] drm/msm/dpu: simplify RM code
Date: Sat, 22 Jan 2022 00:06:12 +0300	[thread overview]
Message-ID: <20220121210618.3482550-1-dmitry.baryshkov@linaro.org> (raw)

INTF blocks are not really handled by resource manager, they are
assigned at dpu_encoder_setup_display using dpu_encoder_get_intf().
Then this allocation is passed to RM and then returned to then
dpu_encoder. So allocate them outside of RM and use them directly.

While we are at it, drop the lm_max_width from the RM and simplify VBIF
handling (move creation/destruction to the RM too). Once this and SSPP
handling patches are merged, the RM would handle lifetime of all
dpu_hw_* objects.

Changes since v4:
 - Changes IS_ERR_OR_NULL() to IS_ERR() in dpu_rm_init()
 - Removed if(!null) conditions when calling dpu_hw_intf_destroy() and
   dpu_hw_vbif_destroy()

Changes since v3:
 - Add missing DSPP blocks teardown
 - Remove dpu_hw_blk from dpu_hw_intf
 - move dpu_hw_vbif creation/destruction to the RM

Changes since v2:
 - Dropped DSPP, PP and MERGE_3D patches for now.

Changes since v1:
 - Split into separate patch series to ease review.

Dmitry Baryshkov (6):
  drm/msm/dpu: drop unused lm_max_width from RM
  drm/msm/dpu: add DSPP blocks teardown
  drm/msm/dpu: get INTF blocks directly rather than through RM
  drm/msm/dpu: stop embedding dpu_hw_blk into dpu_hw_intf
  drm/msm/dpu: fix error handling in dpu_rm_init
  drm/msm/dpu: move VBIF blocks handling to dpu_rm
